If the definition of the web is "anything addressable via URI," then the definition of the web is no longer useful. I can imagine a URN scheme for every atom in the universe. Welcome to the web -- you're soaking in it! More seriously, I think that -- if pressed -- I'd say that the identifiers are on the web, but the things are not. Other than that, I believe we would agree??? That said, the origin of this discussion is in relation to Google's launching of AMP for e-mail. The justification was that e-mails are on the web, so it's OK to use AMP to push them forward. A better viewpoint, though one I disagree with, relates AMP to being a better mode of HTML. (As opposed to one of the Web.)
